This European Standard describes the characteristics that fire-retardant treated wood products should exhibit in order that its fire-retardant properties will persist undiminished throughout the desired service life in the anticipated conditions of use. The Standard prescribes the classification requirements for the durability of the reaction to fire performance of fire-retardant treated wood products to be used in interior and exterior end use conditions. The products shall initially meet required reaction to fire classification. For interior and exterior use, limited hygroscopicity shall be verified. In addition, products for exterior use shall meet the minimum durability of reaction to fire performance requirements specific to the end use. The requirements are applicable to wood which has been treated during a production process with fire retardant product applied either by a penetration process or by a superficial process, such as with a film forming or intumescent fire retardant coating. The fire-retardant treated products may be coated with an ordinary paint. Mechanical properties and biological durability of fire-retardant treated wood products are not covered by this European Standard. Paints, coatings and varnishes intended to improve the reaction to fire performance of a construction product when incorporated in situ in the construction works, are covered by ETAG 028 [19]. This Standard may be used as a basis for an approval system.
